Research Overview

Our central research focus is on ocean biogeochemistry and the coupling with the global climate system. Specific scientific topics currently under investigation include:

human-driven climate change & impacts

ocean acidification

marine ecosystem dynamics

ocean and global carbon cycle

ocean interannual variability

air-sea gas exchange

marine sulfur cycling

sub- and mesoscale biological/physical interactions

phytoplankton genomics

Most of our present work involves the use of numerical models and satellite remote sensing (thus "computational biogeochemistry"), but we also have active data analysis, laboratory and sea-going efforts.

Ocean Biogeochemistry Programs and Data Management:

New efforts are underway to improve communication and coordination within the U.S. ocean biogeochemistry community.

Carbon-climate FeedbacksFuture climate warming and changes in the water cycle and ocean circulation will likely decrease the ability of the land biosphere and oceans to store carbon; the resulting carbon-climate feedbacks would accelerate human induced climate-change.

Ocean Iron FertilizationAdding iron to the surface waters in some parts of the ocean stimulates phytoplankton growth. Some have suggested iron fertilization as a method for slowing atmospheric CO2 growth and thus climate change. The approach is quite controversial, however.
